Abstract
This Bechelor thesis is written on behalf of Verisure Innovation AB in Mamö, Sweden. The authors were studying Bachelors of Sience in Electrical Engineering with focus on automation at Lunds Tekniska Högskola, Campus Helsingborg. The main goal of the thesis was to develop a prototype of an alarmsystem for domestic swimming pools. The system was supposed to sound an alarm if a human being or animal were to fall in to the pool. If the prototype was a success the company could decide later if they wanted to proceed with the development of the product and add it to their product catalog. The first thing that was done was to study what kind of sensors, and thereby also which physical phenomena that could be used. After this a short survey of... (More)
This Bechelor thesis is written on behalf of Verisure Innovation AB in Mamö, Sweden. The authors were studying Bachelors of Sience in Electrical Engineering with focus on automation at Lunds Tekniska Högskola, Campus Helsingborg. The main goal of the thesis was to develop a prototype of an alarmsystem for domestic swimming pools. The system was supposed to sound an alarm if a human being or animal were to fall in to the pool. If the prototype was a success the company could decide later if they wanted to proceed with the development of the product and add it to their product catalog. The first thing that was done was to study what kind of sensors, and thereby also which physical phenomena that could be used. After this a short survey of available pool alarms were conducted, the advantages and disadvantages of the products were analyzed. Two alarms were selected and tested to determine their functionality. The developed device consisted of the parts; the sensors, the hardware and the detection algorithm. The sensors that were chosen where piezotranducers, the hardware was composed of two amplifiers and a developmentboard from STmicroelectronics with a ARM-Cortex M4 processor. The software was developed in an onlinecompiler, “mbed” The software controlled the signals that were sent to and received by the sensors; the received signals were first digitalized in an ADC and later run through a detection algorithm to determine if the device should sound the alarm.
